Genotype by environment interaction between aerated and non-aerated ponds and the impact of aeration on genetic parameters in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
A major problem in smallholder Nile tilapia (Oreochromis niloticus) farms is that the achieved production is much lower than under optimal management. One of the main environmental factors contributing to lower production ...
An investigation of links between metabolic rate and feed efficiency in European sea bass Dicentrarchus labrax
Type: Journal Article
Feed efficiency (FE) is the amount of body weight gain for a given feed intake. Improving FE through selective breeding is key for sustainable finfish aquaculture but its evaluation at individual level is technically ...
Breeding for robustness: Investigating the genotype-by-environment interaction and micro-environmental sensitivity of Genetically Improved Farmed Tilapia (Oreochromis niloticus)
Type: Journal Article
The objectives of this study were (i) to quantify the degree of G x E by assessing the growth performance of Genetically Improved Farmed Tilapia (GIFT) across three countries (Malaysia, India and China) and (ii) to quantify ...
Agonistic behaviour and feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
The main hypothesis of the present study was that an aggressive and dominant fish would eat more feed and would be more efficient. To test this hypothesis, estimations of the relationships between agonistic behaviour, ...
Gender-differentiated preferences regarding rohu carp (Labeo rohita) in Bangladesh: A case study
Type: Internal Report
The focus of this case study is the rohu carp genetic improvement program based in Bangladesh. The work forms part of the Sustainable Aquaculture Program of WorldFish and the CGIAR Research Program on Fish Agri-Food Systems ...
Growth performance of three strains of Nile tilapia (Oreochromis niloticus) on four different feeds in Western and Central Kenya
Type: Journal Article
The growth performance of three commercially available strains of Nile tilapia (Oreochromis niloticus) fed one of four different commercially available feeds during nursery and grow-out was assessed in Kenya. Each of the ...
PmPPAF is a pro-phenoloxidase activating factor involved in innate immunity response of the shrimp Penaeus monodon
Type: Journal Article
One of the major steps in the innate immune response of shrimp includes the activation of serine proteinases of the pro-phenoloxidase pathway by the prophenoloxidase activation enzyme (PPAF). In this study, the cDNA encoding ...
Can individual feed conversion ratio at commercial size be predicted from juvenile performance in individually reared Nile tilapia Oreochromis niloticus?
Type: Journal Article
Feed conversion ratio (FCR), the ratio between feed intake and body weight gain, is of major interest for improving aquaculture sustainability through reduced feed costs and environmental impacts. Demonstrating whether FCR ...
AfDB ZAEDP_GIP Inception Report January 2019
Type: Donor Report
This inception report focuses on the methodologies for the implementation of the research and development component of this project. This research component will be implemented by WorldFish, in partnership with the Department ...
European Commission | TRUE-FISH R3.3: Improved protection of biodiversity, in relation to conservation of native species of tilapias in the EAC region. Annual narrative report: September 2021 to June 2022
Type: Donor Report
Tilapia aquaculture systems in EAC region are based on a handful of species, notably Oreochromis niloticus (Nile tilapia). However, there are other wild tilapia species and strains that could be potential candidate species ...
